Self-inductance is the voltage produced by the changing of the electric current through a circuit that contains inductance, which opposes the change in ... more

Mutual inductance is the voltage produced by the changing of the electric current through a circuit that contains inductance, which opposes the change in ... more

In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input ... more

First proposed by Clement D. Child in 1911, Child’s law states that the space-charge limited current (SCLC) in a ... more

Electrical work is the work done on a charged particle by an electric field. The equation for 'electrical’ work is equivalent to that of ... more

Counter-electromotive force (abbreviated counter EMF or simply CEMF), also known as back electromotive ... more

Hooke’s law is a principle of physics that states that the force F needed to extend or compress a spring by some distance X is proportional to that ... more

In electrical and electronic systems, reactance is the opposition of a circuit element to a change of electric current or voltage, due to that ... more

The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is the radius of a sphere such that, if all the ... more

Alternating current power depends on the voltage and the load resistance
